In recent days, current research is going in alternative fuels due to increase in global warming and pollution in all over the world and also very stringent emission norms. In this way, the study on spray progress plays an important role in improving complete combustion and emission of fuel, because it is directly affects the air-fuel mixture formation. The macroscopic spray characteristics of ...

Introduction: During the past planetary surface missions, few instruments have been deployed to directly assess soil physical properties like density, soil strength (internal friction and cohesion), and pressure/sinkage curves, or their spatial variation. Several Soviet lunar missions were equipped with small cone vane penetrometers, and the Apollo astronauts also used two different manual pene...

This study examines the capability of the Relevance Vector Machine (RVM) and Multivariate Adaptive Regression Spline (MARS) for prediction of ultimate capacity of driven piles and drilled shafts. RVM is a sparse method for training generalized linear models, while MARS technique is basically an adaptive piece-wise regression approach. In this paper, pile capacity prediction models are developed...

Abstract. Cone penetration tests have long been used to characterize snowpack stratigraphy. With the development of sophisticated digital penetrometers such as SnowMicroPen, vertical profiles snow hardness can now be measured at a spatial resolution few micrometers. By using small penetrometer tips this high resolution, further details process are resolved, leading many more stochastic signals....
